Sample GSM1896851 Query DataSets for GSM1896851
Status Public on Jun 10, 2016
Title Co-culture replicate 2, 12 hours after heterotroph addition
Sample type SRA
Source name Bacterial culture
Organisms Alteromonas macleodii; Prochlorococcus marinus str. NATL2A
Characteristics strain: NATL2A (P. marinus), MIT1002 (A. macleodii)
timepoint: 12 hours after heterotroph addition
Treatment protocol The heterotroph Alteromonas MIT1002 was added to one set of biological replicates, at a ~equal cellular abundance to Prochlorococcus. Equivalent amounts of media alone were added to the axenic controls.
Growth protocol Prochlorococcus cells were grown in natural seawater-based PRO99 media under constant light
Extracted molecule total RNA
Extraction protocol Culture samples added to cold RNAlater at each timepoint, cells collected onto a 0.2µm filter, and total RNA extracted with the mirVana kit (Ambion)
Strand-specific RNAseq library construction starting with 100ng of total RNA using the dUTP second-strand approach; duplex-specific normalization was performed to reduce ribosomal RNA content in each sample
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
Description T6Alt_2
Data processing Low quality sequence removed using quality_trim (CLCbio) using default parameters
Alignment of paired-end reads to references using the Burrows-Wheeler Aligner V0.7.12
Number of aligned read pairs mapping in the sense orientation to each ORF determined using Python scripts and the samtools package (0.1.19), method after: "Anders, S., Pyl, P. T., & Huber, W. (2014). HTSeq–A Python framework to work with high-throughput sequencing data. Bioinformatics (Oxford, England)."
Genome_build: NCBI accessions CP000095 and JXRW01000000
Supplementary_files_format_and_content: tab-delimited text file with the number of reads mapping to each ORF for all timepoints and replicates, as well as associated annotation data
